Rhetorically, FEAF was based on the pioneering ideas of John Zachman and Steven Spewak, who were regarded as two of many recognised leaders in architecture conceptualisation and enterprise architecture planning12 (page 19). When? TOGAF provides an end-to-end, holistic guidance for an EA practice including the steps and sub-steps required to develop architecture (ADM), a comprehensive collection of artifacts and deliverables necessary to describe architecture (ACF), governance and maturity models, as well as many other diverse recommendations22. The framework consists of 36 cells, each focusing on the enterprises perspective. A matrix for managing enterprise architecture, dtSearch - INSTANTLY SEARCH TERABYTES of files, emails, databases, web data. On the 'Model Patterns' tab, click on the <name> Perspective button and select 'Enterprise Architecture > Zachman' from the list. It provides a structure for organizing information about its business processes and systems. You should avoid having any meta-models or concepts ascribed to multiple cells. document. At first glance, the current literature offers an exhaustive analysis of all existing EA frameworks from all imaginable perspectives. Zachman defines 7 rules for using huis framework: Rule 1: Do Not Add Rows or Columns to the Framework Rule 2: Each Column Has a Simple Generic Model Rule 3: Each Cell Model Specializes Its Column's Generic Model Rule 4: No Meta Concept Can Be Classified Into More than One Cell Rule 5: Do not Create Diagonal Relationships Between Cells This uses rows to represent different perspectives or viewpoints on enterprise architecture (e.g., strategic planning vs. operations). Companies that Use the Zachman framework Both the Government and commercial sectors use the framework. Why? An example of data being processed may be a unique identifier stored in a cookie. The way an enterprise architect uses the Framework is as a guide for the models their team might use to represent the elements of the architecture implementation. It is based on the idea that organizations should be able to answer two questions about any aspect of their business: What does it do? and How does it do it? Therefore, the framework provides a structure for organizing information to find answers to these questions. The ________ department usually manages the computers, computer centres, networks, and. This version of The Framework has a notable design change, the black-to-white gradient vertical banding that moves down its columns. Enterprise architecture and the Zachman Framework bring together these points of view with others to create a complete picture of the architecture moving forward. Some people will have a more data-centric perspective, while others focus on the management hierarchy; some individuals live among the nitty gritty details, while others seek the big picture. Over 100,000 professionals worldwide are certified with BCS. As a result, the Framework indicates the next iteration of SOA beyond Application Architecture should deal with the eight neighboring squares, as shown in the figure below: Leveraging Zachman to extend SOA to the Enterprise Its easily expandable and customizable for different business domains using an extension mechanism UML Profile. The Zachman Framework isnt exactly a methodology, at least not in the way most IT management frameworks are, mainly because it doesnt offer specific processes for handling data. which frameworks propose more guidance on which aspects of an EA practice), this article compares their practical consequences and outcomes (e.g. sales volume, profitability, or. As it is evident from the comparison provided in Figure 1, none of the top four EA frameworks is substantiated by anyones genuine best practices; all of them represent merely renovated replicas of some earlier architecture planning methodologies that were once advertised by consultancies but proved impractical and vanished, except for the Zachman Framework, which represents a superficial attempt to improve on one of those methodologies. As a result, it provides answers to both questions (What does it do?) and (How does it do it?). Select the 'Zachman Framework' pattern. At the present moment, it would arguably be fair to say that the broad interest in the Zachman Framework has already faded away and within the next few years it is likely to be forgotten by the EA community due to its inexplicable practical utility. The Zachman Framework helps companies organize and prioritize the various perspectives on EA, and this organization and prioritization applies just as well when the EA is SOA. (2006) Enterprise Architecture Agility: Roadmapping with EARM, Cutter IT Journal, Vol. geographical locations, logistics, interconnections Youll learn how to implement the Zachman framework and concepts in your own company along with several methodologies and tools that help support the framework. John consulted with influential members of the academic and consulting spheres, eminent data and process modeling leaders, veteran IT distributors, Business Rule connoisseurs, and top tool vendors for their feedback. A framework can be thought of as a template or scaffolding upon which a program or application can be built. communication media. Even worse, instead of being rejected outright as impractical and forgotten, EA frameworks slowly get institutionalised into the fabric of society in the form of university courses and prerequisite certifications for architects, perpetuating themselves and causing permanent cognitive dissonance between rhetoric and reality throughout the EA community. The Zachman framework is a comprehensive and well-defined matrix tool for Enterprise Architecture. Taking into account that TOGAF is aggressively promoted worldwide with varying intensity for at least two decades as a proven EA standard and buttressed by the global infrastructure of consultancies, experts and other commercially motivated supporters, these expenditures can be truly daunting and vastly outnumber the aggregate toll of all other EA frameworks. This iterative approach to EA implementation is a best practice that ZapThink frequently discusses in its research and advisory into how companies can move to Service Orientation. The framework draws on Zachman's experience of how change is managed in complex products. It is up to the analyst to establish the target and boundaries, and those decisions can make a significant impact on the final outcome of the matrix and the initiative or project. However, some architects still like the Zachman Framework because, unlike other EA frameworks, it is easy to use using it does not require studying extensive materials and does not imply doing anything in particular. For example, the business domain includes goals and objectives, strategy execution, value chain, and customers. The Zachman Framework points out that all such views and many more are every bit as important as all the others in obtaining a complete view of the workings of the enterprise. The TOGAF document set is designed for use with frames. Furthermore, even Steven Spewak himself admitted that the vast majority of enterprises that undertake Enterprise Architecture Planning are not successful5 (page 19). Those architects following ADM steps more or less closely and developing at least half of all the deliverables prescribed by ACF will inevitably face analogous problems, experience disappointment and eventually abandon TOGAF as a practical guidance: After an intensive phase of familiarisation and an initial workshop, where TOGAF was presented to the involved stakeholders, we decided: Thanks, too complicated for us25 (page 14). In particular, the article focuses on the four most widely known EA frameworks: the Zachman Framework, FEAF, DoDAF and TOGAF. Overall, the phenomenon of EA frameworks most certainly is a grand management fad that was shamefully swallowed by the EA community. Today, it is widely advertised as the fundamental structure or even ontology for enterprise architecture, whose role in the EA discipline is equivalent to the role of the periodic table of elements in chemistry. You should avoid adding or removing any columns or rows, as you will need them all to gain the complete picture. [] Perhaps in part due to some of these flaws, the TAFIM was abruptly cancelled24 (page 79). The logic is recursive and generic, which means that it can be used to classify or analyze anything related to the enterprise architecture in question. Gartner alone issued nearly a dozen of several hundred dollars-worth reports with its advice on how to analyse, choose and deal with EA frameworks properly3. 10Hobbs, G. (2012) EAM Governance and Organisation, In: Ahlemann, F., Stettiner, E., Messerschmidt, M. and Legner, C. [] The end result is normally incomprehensible to a business-oriented audience and is harder to trace to the business strategy. In the United Kingdom an "Institute" is not an ordinary company: it has a protected and highly-regulated status that guarantees: . Since 2013 he focuses on studying enterprise architecture practices in organisations. For this reason, all the extant analyses of EA frameworks essentially concentrate only on ample promises given by these frameworks and take their promises for granted, but never question them or analyse whether, or to what extent, these promises have actually been delivered. 276-292. Logical represents what a system should functionally provide, system components and their relationships 26Kotusev, S. (2018) TOGAF-Based Enterprise Architecture Practice: An Exploratory Case Study, Communications of the Association for Information Systems, Vol. He is an author of the book The Practice of Enterprise Architecture: A Modern Approach to Business and IT Alignment (now in its second edition), many articles and other materials on enterprise architecture that appeared in various academic journals and conferences, industry magazines and online outlets. The Zachman Framework remains relevant for modern businesses today largely because technology environments have grown increasingly complex, with legacy technology and information scattered throughout the organization, often lost to employees who have moved on to other systems and solutions. Most EA frameworks are less dynamic than modern business toolkits such as Business Model Canvas. As a result of Zachmans brilliant and persistent promotional efforts, what we have today is a purely symbolic taxonomy, which is claimed to be fundamental, but is apparently based on inappropriate and confusing assumptions, cannot classify real EA artifacts, has no demonstrated examples of its practical application, no use cases in organisations, no implications for EA practitioners anddoes not add any theoretical or practical value to the EA discipline, as discussed earlier. 17DoDAF (2004) DoD Architecture Framework, Version 1.0 (Volume I: Definitions and Guidelines), Arlington County, VA: Department of Defense (DoD). From this perspective, TOGAF can be ironical viewed as a trash can of random EA-related ideas, where something useful can occasionally be found, but only by mature EA practitioners whoalreadyknow all of that, understand what to look for and how to interpret it properly. 9Zachman, J.

Unified Modeling Language (UML) is a descriptive visual language providing scalable diagrams used for standardizing software development. 11-34. During the four-day hands-on modeling workshop you will look at real life examples of the Zachman Framework and learn how to build and implement primitive models. For an enterprise, the what represents the information that flows through the organization and its extended enterprise; the how represents the functions and capabilities of the various parts of the organization, including the business processes; the where consists of the network that pulls together the information and functions, both in the technical sense as well as in the business sense of a network of business relationships; the who is the people or the organization itself; the when includes all scheduling and timing issues throughout the company; and the why represents the motivations of the business to take the actions it doesin other words, the business strategy.
